Creampie (also known as internal ejaculation, nakadashi, and breeding and seeding in same-sex contexts) is a sexual act, commonly featured in pornography, in which a male ejaculates inside his partner's vagina or anus without use of a condom, resulting in visible seeping or dripping of semen from the vagina or anus.
Internal ejaculation shots are a comparatively recent development in pornography; they are not found in early pornographic films. The use of the word creampie to describe such scenes originated in U.S. pornography in the early 2000s.
Internal ejaculations, followed by images of semen dripping from the anus, are sometimes depicted in bareback gay pornography, where they are referred to by the term breeding or the reverse money shot. Breeding is sometimes followed by felching, which involves sucking the semen from the partner's anus.
In straight pornography, sexual activity is often followed by a facial, pearl necklace or other visible ejaculation. Creampie scenes depart from heterosexual pornographic convention in favor of a depiction that more closely mimics sexual activity as performed in ordinary life; they have been called the "counterimage" of facials. Perhaps following the example set by gay pornography, they have become a popular subgenre within heterosexual pornography since the turn of the century, featuring both vaginal and anal ejaculations. In some creampie films, both gay and straight, sexual activity, including internal ejaculation, are followed by performers licking up the semen that has dripped from their bodies. Some pornographic films use an artificial semen substitute to simulate or enhance creampie shots.
Examples of heterosexual pornographic film series featuring creampies include Cream Filled Teens and Internal Cumbustion. In male homosexual pornography, Treasure Island Media is a notable representative, its title Breed Me (1999) having been noted as one of the "earliest and most notorious" in the genre.
